I have removed this lockring using a hammer and punch, but I had always intended to make a better tool, which should not be difficult. First you SG a piece of 1/4" steel plate to about 50mm diameter and mark it out for drilling such that you have one drilled and tapped M5 hole centred on every cutout in the lockring that you want to drive with a peg. The pegs are made by grinding the ends of 12mm or 16mm 12.9 grade caphead screws. These are held in place using locknuts. A connector nut can be welded onto the plate; this will allow the tool to be held. If you enlarge the centre hole prior to welding, the tool can be prevented from slipping in use using a length of studding or similar.
Sorry Brucey, what does SG mean :?
At the last count:- Peugeot 531 pro, Dawes Discovery Tandem, Dawes Kingpin X3, Raleigh 20 stowaway X2, 1965 Moulton deluxe, Falcon K2 MTB dropped bar tourer, Rudge Bi frame folder, Longstaff trike conversion on a Giant XTC 840 :D

SG = Spin Grind; look for my post entitled 'how to SG' if you want to know more.

FWIW if you have no welding skills/facilities, it matters not; you can bolt a handle in position using the peg bolts.

True, but it's no longer the late 80s, or so they tell me. Not sure how easy it would be to get one to suit now.
... .tell me about it - music's terrible now.... I miss the power ballads, big hair, music in major keys only, simple lyrics and a complete lack of irony...
